![either conical or divided, which are highly vascular and project into the epithelial layer. Unlike the vulvar mucous membrane, that of the vagina seems to be destitute of glands. Beneath the epithelial layer is a submucous tissue containing a large number of elastic and some mus- cular fibres, derived from the muscular walls of the vagina. These are strong and well developed, especially toward the ostium vaginse. They consist of two layers—an internal longitudinal and an external circular— with oblique decussating fibres connecting the two. Below they are attached to the ischio-pubic rami, and above they are continuous with the muscular coat of the uterus. The muscular tissue of the vagina Fig. 17.

Its vascular arrangements, like those of the vulva, are such as to constitute an erectile tissue. The arteries form an intricate network around the tube, and eventually end in a submucous capillary ])lexus fhjiii which twigs })ass to supply the papillse; these again give origin to venous radicles which luiitc into meshes freely interlacing with each other and forming a well-marked venous plexus.' 2.
